Crowded in summer
It is about 20 minutes from the town of Durango, and is a beautiful little park. It is awesome in winter time (no camping allowed) for xc skiing and snow shoeing, and in summer is a very popular spot for weekenders. There are several trails around the park and lake that leave right from the campground.
Sites are semi private, you are not camped right on top of your neighbors and the picnic tables were great. Just watch out for bears and make sure your food is properly stored as they know this is a hot camping spot. It can get a little loud on weekends.
